BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention concerns an electrical contact that is used to terminate a flat conductive member formed by disposing foil-form conductive parts on one or both sides of a flat insulating body.
BACKGROUND OF THE INVENTION
For example, the connector shown in FIGS. 7 to 9 (see U.S. Pat. No. 3,247,316) has been known in the past as an electrical connector used to terminate a conductive member consisting of a foil-form metal sheet.
As is shown in FIG. 7, electrical connector 100 has two facing plate parts 101 and 102 that are connected at one end; these plate parts are formed by punching out and bending a metal plate. Teeth 104 and teeth 105 that face the teeth 104 are formed on the upper and lower plate parts 101 and 102 so that the teeth extend toward each other. The teeth 104 and teeth 105 are alternately disposed in two rows on the upper and lower plate parts 101 and 102.
In FIG. 8, a conductive member 110 consisting of a foil-form metal sheet is inserted between the upper and lower plate parts 101,102 of the electrical connector 100. As is shown in FIG. 9, the upper and lower plate parts 101,102 are pressed together, so that teeth 104 pierce the conductive member 110, and so that teeth 105 pass through the conductive member, thus terminating the conductive member 110 in the electrical connector 100. Teeth 105 of each plate part also pass through holes 106 defined through the other plate part at teeth 104 thereof, whereafter ends of teeth 105 are flattened and are bent over portions of the conductor member also extruded through holes 106. In FIGS. 7 to 9, 103 indicates an electrical wire connecting part that is used for a crimped connection of an electrical wire 120.
However, in this conventional electrical connector 100, when the conductive member 110 is terminated in the electrical connector 100 and teeth 104 are caused to pierce the conductive member 110, and teeth 105 are caused to pass through the conductive member, the following problem arises: i.e., the connecting portions of the conductive member 110 that connect with the teeth 104 and 105 are structurally weak, so that contact of the electrical connector 100 with the conductive member 110 is unstable.
SUMMARY OF THE INVENTION
In U.S. Pat. No. 4,952,177 is disclosed a clamp for an electrosurgical electrode in which one or two U-shaped electrical contact strips engage tab electrodes and are contained in a housing, with upper strip portions becoming pressed firmly against the electrodes upon pivoting of a lever to cam the upper strips toward the electrodes for embossments on the upper strips to press the electrodes against depressions in the lower portions of the strips, for electrical connection.
Accordingly, the object of the present invention is to provide an electrical contact that insures stable contact with a conductive member formed by disposing foil-form conductive parts on one or both sides of a flat insulating body, when such a conductive member is terminated.
The electrical contact of the present invention has a terminating section that terminates a flat conductive member formed by disposing a foil-form conductive part on one or both sides of a flat insulating body, and an elastic contact part that elastically contacts the conductive member. The electrical contact is characterized by the fact that the elastic contact part has [a] a string arm that has an embossment with a substantially spherical surface that presses against the conductive member, and [b] a substantially circular hole that faces the embossment, and that has a rim that is contacted in a substantially circumferential state of contact by the conductive part of the conductive member pressed by the embossment. A free end of the spring arm includes anchoring portions that lock with side walls of the base when pressed downwardly.
DETAILED DESCRIPTION
Preferably, the electrical contact of the present invention may also be constructed so that the contact has a terminating section that terminates a flat conductive member formed by disposing foil-
